RE: [SLUG] Ethernet dropouts..

[George Vieira <georgev@nospam.citadelcomputer.com.au>]

These guys are programmers who usually start up a telnet session which
automatically creates a DISPLAY enviroment for X to connect to.
They just type "window" and hit enter which runs a "nohup gnome-terminal &"
and they create as many windows as they need.

They are all connected to the 1 coax line into a small 10BaseT hub with a
BNC connector for the programmers (I'm in the middle of getting a 24 port
10/100 switch). The cabling runs along the wall in a kick panel and this
problem has only started since the upgrade to the Linux box.

I'm running on one of the ports on the 10 port hub and it's failing for me
too... only since yesterday though.

Not much help to you, but these cards have worked fine for me for over
two years.

10Base2 makes me ask if there is any exposed cables that may have been
damaged or have equipment resting on them (like a filing cabinent that
squashes the cable when the top draw is pulled out -{:-).

Also 10base2 legs can benefit by a working of all connections - dirty
office syndrome leads to crud build up on the connection. Yep, it
sounds like bullshit, but it happens.

Nope, start logging all problems and look for common factors.
	Are they all on the one 10base2 leg,
	What were they doing in X?
	How many sessions did they have open, 
	etc.

There are a lot of possibilities to be eliminated.
